Question

What is the potential energy of a rock that weights 100 Newtons that is sitting on top
of a hill 300 meters high?
joules

Answer 1

Answer:

Us we know mass is constant any where .

Given :-

W=100N                                               gravity=G=10 meter per second square

H=300M

W=M*G

w=m*10m/second square

100=M*10

M=10kg

P.E=M*G*H

P.E=10*10*300

P.E=30,000J
